TO ALL WI-IOM I'l MAY CONCERN:

Be it known that I, PETER Low, of Cleveland, in the State of Ohio, have invented certain new and useful Improvements in Cooking-Stoves; and I hereby declare that the following is a true, full, and exactl description of thesame, reference being had to the accompanying drawings, an'd to the letters of reference marked thereon. In the drawings annexed, which make a part of this specification- Figure 1 exhibits a side-view of my stove.

Figure 2 is a front elevation of the same.

Figure 3 is a front view ofthe ribbed back piece ofthe dre-box.

The letter A represent's thebody of the stove open at the two sides to get access to the haking-ehamber, and otherwise constructed similar to cooking-stoves in common use. B represents the grate with which the tire-box is furnished. The bars of the grate are constructed at their inner end with a convex metal rim, t, perforated with a dubleseries of holes, s, running lengthwise of the rim, and also with a number of lateral ribs, theV object of these ribs being to prevent the coal, from coming in contact with holes s, and thus to prevent the admission of nir from beneath the grate. At the back of the fire-box is placed the adjustable plate C, furnished with vertical ribs, with a series of holesbetween them. Behind theI plate C is the partition D, against. which the plate C rests. The said partition has a hollow rim, e, at top, with a number of holes in it, through which the air can have passage into the tire-box, and is also supplied with vertical ribs n, the said ribs being intended to prevent plate C from, pressing against the partition D, and thus preventing the nir from circulating between the plate and partition. Each end of the fire-box isvsupplied with a ribbed end piece, g, which is made concave at the inner surface, and has a rim at top-to prevent its {itting elose to the dre-box. The end pieces ghave numerous perforations for the passage of air received through holes made in the external casing of the stove.

By the above-described devices it will be seen that currents of air will be received into the fire-box from the rear and ends as well as from beneath the grate, und lthus combustion great-ly promoted. It will be remarked that the end pieces g are adjustable,and when burnt out can be-remo'ved and others put in their place.

Having thus described my invention, what I'claim, and desire to secure-by Letters Patent, is

I. The grate-furnished with the convex rim t, constructed as and for the purpose herein set forth.

2. The adjustable ianged and perforated ribbed end pieces g, constructed in the manner herein described.

3, The combination ofthe rim t, the end pieces g, and rim e, the whole constructed and operating substantially as herein described.

In testimony that I claim the above as my own I hereby ax my signature in the presence ofA two witnesses.

PETER LOW.
